Digestive Tract

The human digestive system is a complex and multicomponent organ that performs the function of digesting food. The alimentary canal begins with the oral cavity, where food is chewed, and ends with the anal canal, which removes undigested food from the body.

The digestive process begins with the process of chewing food, which breaks it down and makes it more accessible for digestion. Then the food enters the stomach, where primary digestion occurs under the action of gastric juice containing enzymes.

From the stomach, food enters the small intestine, where the digestion process continues under the influence of bile and intestinal juice. This is where nutrients are absorbed into the blood and lymph.

After the small intestine, food enters the large intestine, where water is finally absorbed and feces are formed. In the large intestine, the process of fermentation and rotting of food remains under the influence of bacteria also occurs.

At the end of the digestive canal is the anal canal, which ends in the anus. This is where feces are removed from the body and removed to the outside.

Thus, the human digestive tract is a complex and multi-stage process that ensures the absorption of nutrients and the removal of undigested food debris from the body.

DIGESTIVE TRACT1 - (tr. guttalis) is a section of the digestive canal1, from the oral cavity to the rectum. In turn, the digestive canal1 itself consists of two successively connected segments: the duodenum (corpus duodenum) and the colon (colon), which have valves (For reference: in Russian the term “internal channel” is more common. - Translator’s note.)

The duodenum (duodenum, J9 - in animals) passes into the jejunum. In both cases, digestion
